The correct answer to this open question is the following.
Although the question has no options, we can answer the following.
The first person to recognize and name an australopithecine was Raymon Dart.
It was scientists and Professor Raymond Dart who in 1924 found the humanoid fossil called "The Taung child," in Africa. Then, Dart named the species as an Australopithecus, identifying it as a southern human-ape from South Africa. The scientific community did not accept Professor Dart's theory immediately. It had to pass almost twenty years to officially accept the term Australopithecus.
